DSL file encoding [message #1121305]

Hi,

i'd like to have all DSL files for my language created by eclipse (i.e. *.mydsl) encoded in UTF-8. Eclipse encodes the files in the system's standard encoding.

I added the encoding statement to the Generator as described in the documentation:

Generator {
  encoding ="UTF-8"
  ...

My expectation was, that every newly created file will be encoded in UTF-8, but this isn't the case.

Any ideas what could have gone wrong?

Hi,

i think you have to implement a org.eclipse.xtext.parser.IEncodingProvider

I did implement a IEncodingProvider returning UTF-8 and bound it in the Runtime and the UiModule. The Runtime part works as expected. The standalone parser interprets the files as UTF-8.

But Eclipse still produces files encoded in the system default codepage.

P.S: did you consider to change workspace encoding?

Creating files in Eclipse: select folder -> new -> file -> enter filename

That creates files in the default workspace encoding. Of course this can be changed by the user, but I'm looking for a way to set UTF-8 as default for my language's projects, so I don't have to tell the user to set his encoding.

Is this possible?

Hi,

sorry i have no idea on that it is not an xtext specific problem.
if you use the project wizard you can create with

fragment = projectWizard.SimpleProjectWizardFragment auto-inject {
    		      generatorProjectName = "${projectName}"
    		 }

(dont forget to merge plugin.xml_gen)

i think you can customize the code to use utf-8 as encoding. (you have to digg into the code on that yourself)

I already toyed around with the SimpleProjectWizard, but it seemed like I need some time and a lot of know-how to get the projects the way I want them. I'll look into that.

Thanks
